VMS Options#

These -m options are defined for the VMS implementations:

-mvms-return-codes#

Return VMS condition codes from main. The default is to return POSIX-style condition (e.g. error) codes.

-mdebug-main=prefix#

Flag the first routine whose name starts with prefix as the main routine for the debugger.

-mmalloc64#

Default to 64-bit memory allocation routines.

-mpointer-size=size#

Set the default size of pointers. Possible options for size are 32 or short for 32 bit pointers, 64 or long for 64 bit pointers, and no for supporting only 32 bit pointers. The later option disables pragma pointer_size.
